Internal Wire For POWER CABLE

- Nov 03, 2017 -

The connector has four pins, but only two wires, the color is usually one red one black or one orange a black, properly connected to the chassis for the speakers to use. The plug on this switch line and the corresponding pins on the motherboard are generally marked with speaker words.POWER CABLE

ome computers after the normal start will be issued by the Speaker "beep" of a sound, or can not start normally, through the horn issued corresponding alarm sound, for the user to solve the problem to provide help. However, some motherboards are already integrated with speakers, so there is no need to connect the speakers on the chassis.POWER CABLE

The Wire's internal wire is too poor, when the power of the moment due to the computer ATX power supply Internal high-voltage capacitor also to instantaneous charge, at this moment, the current is relatively large, instantaneous maximum current can reach more than 6, if the computer ATX power supply inside the buffer circuit is not designed to have a greater impact current through, also known as instantaneous surge.POWER CABLE

That is, in that moment, the computer power line if the use of low-quality materials to do the wire, its resistance is relatively large, heat also big, an instant a wire will burn. (Damaged in the middle of a wire or a certain position)POWER CABLE

The connector of the line and the plug, the connector of the power cord and the host ATX Power Connector, if these two interconnected ports or contact is too loose, it is easy to cause electric spark, that is, the conductor metal and metal plate contact between the poor contact area too little, the area is too small to allow the current through the smaller, coupled with large resistance is easy to burn out,POWER CABLE

Because the current reduction is not enough to reduce the calorific value, because the heat q=i*i*r, it is obvious that I slightly reduce and R slightly increase does not change the overall heating trend Q. So the interface is easy to see the burnt blackened.POWER CABLE
